A quality port job can add power,and ECONOMY, even while retaining stock parts! Because casting imperfections are removed, not only are power gains likely, but more even airflow promotes even combustion, which promotes cleaner emissions. More airflow, more power... less throttle angle required to hold a speed... likelihood of better mileage (if you can resist the urge )

BIG EDIT - Since I ALWAYS recommend a minimum level of work, I decided that pricing should reflect that minimum amount of service. I've condensed the bowls, and seats, tapering the guides, deshrouding and balancing the chambers, and the exhaust port re-taper into the minimum service I'll offer.

Hmmm, I think I heard you..., "What does an unported short radius look like??" Well I don't have a photo of those (ports above) prior to work, but here is another head showing the short radius before...

VERY shortly I'll be offering flowbench services. I have not as of yet figured out how much I'll be charging. I also will not be offering this until I feel I can guarantee my #s.

To do this I've recently acquired some new equipment....

and so I KNOW I'm accurate with setting valve lift...

I've also had quite a few people help "train" me on my own equipment

the math involved in the flowbench makes my brain hurt ... so I've had a few people help dumb the theories down for me to simple actions(keystrokes) to operate "the tool" = flowbench

One service I'm planning to add to a minimum service.... is to show on a flowbench spread sheet, the progress of one cylinder from dirty/cruddy/old, to cleaned up original casting, to fully ported and ready to deliver.

I also plan on doing full port matching. This will be based on an hourly rate I'll set in the future.

Now TRUE port matching has nothing to do with hogging out the hole to fit the gasket...

What TRUE port matching is.... has EVERYTHING to do with making sure EACH PORT flows the same @ each lift point so that each cylinder get an IDENTICAL fuel/air charge so ALL cylinders are making the same power.

Sorry for the hijack, But is there a post somewhere with before&after flow numbers, or a percentage if you don't want give up the numbers? d:)bI haven't taken look at much of your stuff, kinda gave up after too many polished ex port pics.

Why yes... I DO have PROOF of what I can do......

the little red arrows are pointing to 7.1mm lift, or cams from 1988+ 4AGE engines

the blue arrows are 7.5mm lift from the earlier pre 1988 4AGE engines

As the arrows show even with stock cams, my port work improves flow. Btw, those numbers were back in 2009, my exhaust port work has improved since then.

don't have one on hand now... but I can get a hold of one in 3 to 4 days... send me an email to oldeskewltoy@yahoo.com

As to what I've been doing recently..... I'm porting a head from a Mazda(Ford) 2.2 liter turbo. A few pics for you from that job....

Hi this is slightly unrelated but I figured since 4age head work is what you do, you might know these numbers off the top of your head

hello all, I'm in the middle of rebuilding a Small port, it's a mild build, balanced bottom end, .020 over, etc........ I am sooooo close to having it back in my hands but my machinist just needs a couple specs before I can get it. so i was wondering if anyone would know off hand some numbers...WHAT IS THE OE HEAD GASKET THICKNESS COMPRESSED?OE PISTON TO DECK CLEARANCE?OE VALVE TO PISTON CLEARANCE?thank you for your help

1.2mm is the OEM gasket compressed thickness.

OE Piston to deck is unreliable... I've measured USED engines I've ASSUMED are original @ .002" to .003"

The OE valve to piston is somewhere in excess of 7.5mm because the engine is none interference and so with stock cams(7.5mm lift), the pistons do not hit if you break a belt.
